[0029]
The various room boxes (2) (2)... Manufactured in the factory in this way are sequentially lifted by crane wires (28) (28). At the time of lifting, as shown in FIGS. 1 and 6, the crane wires (28), (28) are radiated from the upper center of the ceiling panel (10) toward the eyebolts (29) (29). The tensile force of these crane wires (28), (28) ... is not only transmitted to the floor panel (11) side through the shaft frames (40) (50) (57) (58) (59). Also on the open part (60) side, the signal is transmitted to the floor panel (11) side through the cane (62) (62) and the temporary pillar (63). Accordingly, the tensile force of the crane wires (28), (28),... Will be evenly distributed throughout the room box (2), thereby preventing (2) deformation of the room box.
[0030]
In particular, because the wand (62) (62) is arranged in a C shape along the direction of operation of the crane wire (28) (28), the crane wire ( 28) The tensile force of (28) can be efficiently transmitted to the floor panel (11) side, and the temporary pillar (63) between the eyebolts (29) and (29) on which the crane wires (28) and (28) are hooked Therefore, the buckling of the long cross member (17) of the ceiling frame (15) can be reliably prevented. Moreover, even when an impact is applied to the room box (2) when loaded on the truck from the lifted state or transported by the truck, the cane (62) (62) and the temporary pillar (63 ), The shape of the box can be reliably maintained.
[0031]
The room boxes (2) (2)... Transported to the site by the truck are again lifted by the crane wires (28) (28). Then, the wands (62), (62), the temporary pillars (63), and the various fittings (26), (36) are removed from the room boxes (2), (2), and the room boxes (2), (2),. A building is constructed by sequentially stacking structural beams, room boxes (2), (2).
[0032]
In addition, this invention is not limited to the said embodiment, Of course, many correction changes can be added in said embodiment within the scope of the present invention.
[0033]
【The invention's effect】
As is clear from the above description, according to the room box of the present invention, the reinforcing temporary member is simply attached to the open portion side via the L-shaped joint metal fitting, so that the structure is weak in combination with the frame-shaped frame. Even so, it is possible to prevent deformation at the time of lifting with a crane wire without using a large jig as in the prior art.
[0034]
In addition, a plurality of mounting holes for attaching temporary materials are formed along the edge of the ceiling or floor on the vertical piece of the joint metal fitting, so the position of temporary materials can be finely adjusted in the direction of the edges. The temporary material can be attached with high accuracy.
[0035]
Furthermore, since the joint fitting and the reinforcing temporary material can be removed, the design is not hindered and can be reused when another room box is transferred.
